"Nitrogen oxides are common pollutants found in most of the air in the United States. You can be exposed to nitrogen oxides outdoors by breathing air that contains it, especially if you live near a coal-burning electric power plant or areas with heavy motor vehicle traffic. You can be exposed to higher levels if air pollution and smog levels are high.
You can be exposed at home if you burn wood, or use a kerosene heater or gas stove.
You can be exposed at home or at work, indoors or outdoors, through smoking cigarettes or breathing second-hand cigarette smoke.
You can be exposed at work if you work in a facility that produces nitric acid, explosives such as dynamite and TNT, or welded metals.
How can nitrogen oxides affect my health?
Exposure to high industrial levels of nitric oxide and nitrogen dioxide can cause death. It can cause collapse, rapid burning and swelling of tissues in the throat and upper respiratory tract, difficult breathing, throat spasms, and fluid build-up in the lungs. It can interfere with the blood's ability to carry oxygen through the body, causing headache, fatigue, dizziness, and a blue color to the skin and lips.
Industrial exposure to nitrogen dioxide may cause genetic mutations, damage a developing fetus, and decrease fertility in women. Repeated exposure to high levels of nitrogen dioxide may lead to permanent lung damage. Industrial exposure to nitric oxide can cause unconsciousness, vomiting, mental confusion, and damage to the teeth. Industrial skin or eye contact with high concentrations of nitrogen oxide gases or nitrogen dioxide liquid can cause serious burns.
Long-term exposure to nitrogen oxides in smog can trigger serious respiratory problems, including damage to lung tissue and reduction in lung function. Exposure to low levels of nitrogen oxides in smog can irritate the eyes, nose, throat, and lungs. It can cause coughing, shortness of breath, fatigue, and nausea.
